Cloudera Manager can manage multiple clusters, however each cluster can only be associated with a single Cloudera Manager Server or Cloudera Manager HA pair. Once you have successfully installed your first cluster, you can add additional clusters, running the same or a different version of CDH. You can then manage each cluster and its services independently.
On thetab you can access many cluster-wide actions by selecting to the right of the cluster name: add a service, start, stop, restart, deploy client configurations, enable Kerberos, and perform cluster refresh, rename, upgrade, and maintenance mode actions.
Cloudera Manager configuration screens offer two layout options: classic and new. The new layout is the default; however, on each configuration page you can easily switch between layouts using the Switch to XXX layout link at the top right of the page. For more information, see Configuration Overview.
